Question

我应该如何根据我的循环参数重新定义父<address>节点并使用属性向其添加子<addressline line="">。目前我只将数据添加到<address>节点。

当前代码：

public class PDFXml {

        public string Filename { get; set; }
        public string Filepath { get; set; }

        public string Name { get; set; }
        //redefine Address node and add children
        public string Address { get; set; }
        public int PostIndex { get; set; }

        public void CreateXML(string pdfPath, string savePath) {

            HeaderInfo headerinfo = new HeaderInfo();


            var pdfxmldata = new PDFXml() {
                Filename = Path.GetFileName(pdfPath),
                Filepath = pdfPath,
                Name = headerinfo.GetFullName(pdfPath).Trim(),
                //Address = "??????????",
                PostIndex = headerinfo.GetPostIndex(pdfPath),
            };

            for (int i = 0; i <= 3; i++) {
                //Add addressline element to <address> - <addressline line = "i"></addressline>
            }

            var filestream = new FileStream(savePath + @"\" + Path.GetFileNameWithoutExtension(pdfPath) + ".xml", FileMode.Create);
            new XmlSerializer(typeof(PDFXml)).Serialize(filestream, pdfxmldata);
            filestream.Close();

        }
    }

我当前的XML

<pdfxml>
    <filename></filename>
    <filepath></filepath>

    <name></name>
    <address></address>
    <index></index>
</pdfxml>

我想要这样的事情：

<pdfxml>
    <filename></filename>
    <filepath></filepath>

    <name></name>

    <address>
       <addressline line="1" ></addressline>
       <addressline line="2" ></addressline>
       ...
       <addressline line="999" ></addressline>
    </address>
    <index></index>
</pdfxml>

介绍新课程：

var child = new obj();
child.method();

将PDFXml的属性更改为：

public class AddressLine
{
    [XmlText]
    public string Text { get; set; }
    [XmlAttribute("line")]
    public int Line { get; set; }
}

public class Address
{
    [XmlElement("addressline")]
    public List<AddressLine> AddressLines { get; set; }
}

像这样创建实例：

//Changed Address to AddressL
public Address AddressL { get; set; }

按如下方式填写数据：

//Changed Address to AddressL
var pdfxmldata = new PDFXml()
{
    ...
    AddressL = new Address { AddressLines = new List<AddressLine>() },
    ...
};

使用循环添加XML节点
